Agree. Software controls everything now days. I find it more responsive in sport mode than non-sport mode. To me, the throttle tip-in is better. I tend to use sport mode around town. It might cost me a bit of fuel, but it drives better.

This thread is one of the reasons I went with a 6 Speed manual gearbox. So simple, never fails, etc... Hoping you get your issue resolved.

After I got the new update to my DCT it engages immediately and have no lag. No roll back either.
Maybe you would need the update. BMW has different programming for problematic cars. When I worked at Bavarian BMW in Michigan their was code for cars with shifting issues that new cars that came from the factory didn't have. Of course that was 10 years ago MINI was similar. |

Sounds like dealer time for a reflash.

I'm wondering if this would fall under a manf defect and safety hazard? I guess if enough people complain or the NTSB gets involved there might be a recall.

My DCT engages P/N -> D/R almost like a normal automatic. An it can also transition from D/R back to P/N as quickly.
When I'm stop and go on an uphill, my car tends to rollback sometimes! On other instances, it remains in place. I'd say it's 50/50 when it does and doesn't roll back. However, from a stop while in D/M1/M2 and I let go of the brake pedal and step (slightly) on the accelerator. My car lags for half a second and pounces forward as if trying to catch up for the time it's lost. This isn't necessarily cured by engaging sport button with M1/S1...In fact, it's more evident. Do I need the update? |

Is NHTSA and the NTSB the same? I remember I had a issue with my dads 09 Corolla steering, I notified NHTSA and TOYOTA was adamant about getting it fixed. Toyota did an alignment, new front tires and also checked the software. The car drove much better after that.

The car simply does not react from slow speeds or stops. It does not rev, it does not change gears, it does nothing. The expectation is not that the car begins to roll forward when the foot is off the brake. The expectation is that the car moves when I press the accelerator. The failure of the car to react in this situation happens to me at least half a dozen times per day, and as Battery described, it can be downright dangerous, not just because of the lag in reaction, but because of the sudden lurch after the lag. The behavior is not driver dependent (my dad and even my wife have noticed it). Driving in D/S, Manual, with or without Sport, and with or without DTC on/off in any form makes absolutely no difference. No software update from the dealer has fixed it either. I have the latest SIB and dealer claims the transmission operates as designed. As others have noted, this is not a mechanical issue! BMW's M-DCT does not have this problem. This is a programming/software issue. I heard rumors that the software update from the PPK 1 alleviates the issue. Can anyone confirm or deny this? I suppose if a 135is owner still has the same issue, that would answer that question.

hey 02rsxpilot read through this thread
http://www.1addicts.com/forums/showthread.php?t=1033690 I had the same or similar issue as you and got the update noted in the above thread and car is now night and day different. Zero hesitations, zero lag at all. I think it's SIB 12 15 14. Your SA should know what to do with that, it describes the same/similar issue that you have and the remedy - software update. I cannot recall what the software version is but I think it's in that thread. Good luck. |

Multiple threads on this subject but since SIB 12 15 14 I've had zero issues. I do have PPK1 so in not sure if that makes a difference. I'm very satisfied with the fix. I've tried every which way to make it fail and so far nothing upset the transmission.
